Biowaffen: Alte Gefahr, neue Risiken durch KI

Advancements in biotechnology and the accelerating power of Artificial Intelligence raise concerns regarding the potential misuse of these technologies for biological warfare. Progress in biotechnology allows for more precise analysis and modification of pathogens, which, when combined with AI's capacity to process large datasets quickly, could expedite research into biological weapons development. Experts express concern that this technological convergence could increase the risk of weaponization by non-state actors.
The article outlines the definitions and international legal framework surrounding biological weapons. Biowarfare involves releasing biological agents like pathogens to harm humans, animals, or plants, requiring both a biological agent ("Agens") and a delivery system ("Trägersystem"). These weapons are grouped with chemical and nuclear weapons as ABC weapons. While chemical weapons cause immediate toxicity, biological weapons cause infectious diseases, leading to consequences that can spread between people.
Internationally, the Biological Weapons Convention (BWC) prohibits the development, production, storage, transfer, and use of biological weapons. Unlike chemical weapons, there is no equivalent international inspection system for biological weapons, relying instead on transparency and trust. The difficulty in controlling these weapons stems from the dual-use nature of the underlying scientific research, where legitimate medical or defense applications can simultaneously serve military ends.

* Künstliche Intelligenz könnte künftig auch für die Entwicklung biologischer Waffen missbraucht werden.
* Fortschritte in der Biotechnologie ermöglichen eine genauere Analyse und Veränderung von Krankheitserregern.
* KI kann Datenmengen schneller auswerten.
* Der Chef des MI5, Ken McCallum, warnte im Oktober 2026, dass KI die Gefahr durch Biowaffen erhöhen könnte, insbesondere in den Händen nichtstaatlicher Akteure.
* Anthropic berichtete im September 2026 über Versuche von Forschenden, Claude für Gain-of-Function-Forschung und Untersuchungen von Vogelgrippe-Varianten zu nutzen.
* Die Forschung kann sowohl medizinische Vorsorge als auch militärische Zwecke dienen.
* Biologische Waffen umfassen biologische Wirkstoffe und ein Verbreitungssystem (z.B. Raketen, Sprühsysteme).
* Biowaffen werden zusammen mit Atomwaffen und Chemiewaffen zu den ABC-Waffen gezählt.
* Chemiewaffen verursachen Schäden durch giftige chemische Stoffe innerhalb von Sekunden oder Minuten; Biowaffen verursachen Infektionskrankheiten, deren Wirkung erst nach Stunden, Tagen oder Wochen einsetzt und können sich verbreiten.
* Die Biowaffenkonvention (BWC) trat 1975 in Kraft und verbietet die Entwicklung, Herstellung, Lagerung, Weitergabe und Nutzung biologischer Waffen.
* Das Kontrollsystem für Biowaffen ist im Vergleich zu Chemiewaffen nicht vergleichbar; es basiert auf Transparenz und Vertrauen.

The persistence of biological weapon concerns stems from the fundamental "dual-use" nature embedded within biotechnology. The core difficulty in control is that the same scientific tools—those used for developing life-saving medicine or understanding natural disease evolution—are inherently applicable to creating harmful agents. This creates a dilemma where legitimate research pathways overlap with potential malicious applications, making strict separation extremely challenging.
The dynamic described highlights a tension between rapid technological advancement and the necessary slow, deliberate implementation of international control mechanisms. The fact that established prohibitions like the BWC exist alongside the reality of historical misuse (such as anthrax dispersal following the September 11th attacks) suggests that legal frameworks alone are insufficient; systemic vulnerabilities related to dual-use research must be continuously addressed.
The mechanism for evasion is reinforced by the inherent ambiguity in defining and monitoring biological threats. Because an attack may mimic a natural outbreak, detection relies on post-hoc investigation, which allows malicious actors time to operate undetected. This reality pushes the discussion from simple prohibitions toward establishing robust, verifiable oversight mechanisms that address the convergence of AI capability and biological research, ensuring that technological novelty does not outpace global accountability.
What are the systemic gaps in current international protocols when confronted with AI-accelerated dual-use research? How can systems built on trust and voluntary reporting effectively manage threats where actors may intentionally mask activities as legitimate scientific inquiry?
